Andro Cycle March 3, 2011 Comments Off on 1-Testosterone

Molecular Structure of Testosterone 1-testosterone was a prosteroid that was made illegal in 2005. It is a naturally occurring metabolite for many animals including man that has properties far different from standard testosterone in the body. 1-Test is more of a mild hormone that will give you cleaner gains without a lot of side effects.  The prohormones to this compound is 1-androstenedione, 1-androstenediol and 1-androsterone. Of the three, only 1-androsteroneis still available on the U.S. market.  There might be some 1-testosterone products available in places like the UK and other countries that don’t criminalize hormonal items, but it is very scarce in the US.

1-testosterone would give you clean gains that are very dry and lean in nature. This means you won’t get a lot of bloat or estrogen activity with this prosteroid. The lack of estrogen actually caused most people to stack this steroid with 4-androstenediol or another “wet” compound. This helped potentiate the gains and increase the “comfort” of the cycle. 1-testosterone was never one to put on tons of mass, but it will give you clean gains that are very sustainable.

1-testosterone Structure

1-testosterone has a structure similar to testosterone (4-testosterone is a better description) but the double bond is in a different place.  This slight modification means that the molecule is subject to different metabolism than standard testosterone. It can not be converted to estrogen via aromatase nor can it be turned into DHT. This makes it a very stable molecule and resists most traditional routes of metabolism. Like any non-methyl steroid, it is going to be deactivated in the liver/intestines unless you take something that blocks glucoronidase.

Safety / Side Effects

1-testosterone was safe and effective at reasonable doses. Many delivery forms existed like transdermal 1-testosterone, various ethers and esters and also, sublingual. There was even a company or two that made an injectable 1-testosterone product as well.  You shouldn’t have any liver or kidney stress with 1-test, because it lacks the C17 methyl group.  The main side effect that was reported with 1-testosterone was lethargy. There is something about this molecule that made people tired on cycle. That was another reason people often stacked this molecule. Overall, aside from the risks of androgens in general, 1-testosterone seemed to be pretty mild and hundreds of thousands of people used this once legal supplement.


Due to the updated ban on products containing 1-testosterone, it is illegal to carry and sell this product in the US.  It might still be legal or quasi-legal in other countries, but typically the US is the only country that manufactured this supplement.

testosterone Is Still The Best

The illegal steroid community is starting to discover that testosterone is the best androgen you can take as a man over 21. You want to increase it to balance out the constant bombardment of Xeno-Estrogens in the diet. These come from BPA in soft drinks, which is a strong estrogen along with most other chemicals you drink and eat from plastics. We feel that this increase in testosterone is necessary for the modern man due to the imbalance caused by all of these chemical estrogens in the diet. This is why we feel that prohormones to testosterone are the best thing that a man can use to supplement his diet and reverse this imbalance in their body.

testosterone won’t cause liver stress it also is much milder on cholesterol and shouldn’t cause any blood pressure issues.
